一、简介
yum主要功能是更方便的添加/删除/更新RPM包,自动解决包的依赖性问题,便于管理大量系统的更新问题,其理念是使用一个中心仓库(repository)管理一部分甚至一个distribution的应用程序相互关系,根据计算出来的软件依赖关系进行相关的升级、安装、 删除等操作,减少了linux用户一直头痛的dependencies的问题。 可以同时配置多个资源库(Repository),简洁的配置文件(/etc/yum.conf),自动解决增加或删除rpm包时遇到的依赖性问题,保持与RPM数据库的一致性。
二、软件安装方法及策略

三、官方源
配置CentOS6官方源,步骤如下:
1)执行如下命令,查看yum包
rpm -qa|grep yum
2)执行如下命令,卸载原有源
rpm -qa | grep yum | xargs rpm -e --nodeps
3)下载新的yum包
wget http://centos.ustc.edu.cn/centos/6/os/i386/Packages/yum-3.2.29-22.el6.centos.noarch.rpmwget http://centos.ustc.edu.cn/centos/6/os/i386/Packages/yum-metadata-parser-1.1.2-16.el6.i686.rpm wget http://centos.ustc.edu.cn/centos/6/os/i386/Packages/yum-plugin-fastestmirror-1.1.30-10.el6.noarch.rpm
4)执行如下命令,安装新的yum包
rpm -ivh yum-*
5)下载yum的配置源
wget http://docs.linuxtone.org/soft/lemp/CentOS-Base.repo
修改配置源,修改后的链接如下:
http://download.csdn.net/detail/u011640816/9252933
6)执行如下指令,进行统一更新
cd /etc/yum.repos.d/yum update
四、第三方源
CentOS/RHEL默认的yum软件仓库非常有限,仅仅限于发行版本那几张盘里面的常规包和一些软件包的更新,利用RpmForge,可以增加非常多的第三方rpm软件包. RpmForge库现在已经拥有超过10000种CentOS的软件包,被CentOS社区认为是最安全也是最稳定的一个第三方软件库.
步骤如下:
1、安装yum-PRiorities插件
这个插件是用来设置yum在调用软件源时的顺序的. 因为官方提供的软件源,都是比较稳定和被推荐使用的. 因此,官方源的顺序要高于第三方源的顺序. 如何保证这个顺序,就需要安装yum-priorities这插件了.
# yum -y install yum-priorities
2、安装完yum-priorities插件后,需要设置/etc/yum.repos.d/ 目录下的.repo相关文件(如CentOS-Base.repo),在这些文件中插入顺序指令:priority=N (N为1到99的正整数,数值越小越优先)
一般配置[base],[addons],[updates],[extras]的priority=1,[CentOSplus],[contrib]的priority=2,其他第三的软件源为:priority=N (推荐N>10),以CentOS-Base.repo 为例:
##############################################################[base]name=CentOS-$releasever - Base#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=osbaseurl=http://ftp.sjtu.edu.cn/centos/$releasever/os/$basearch/gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6priority=1##############################################################
3、adobe软件仓
1、添加adobe软件仓并导入密钥
# rpm -ivh http://linuxdownload.adobe.com/linux/i386/adobe-release-i386-1.0-1.noarch.rpm #32位# rpm -ivh http://linuxdownload.adobe.com/linux/x86_64/adobe-release-x86_64-1.0-1.noarch.rpm #64位# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-adobe-linux #导入密钥
2、设置/etc/yum.repos.d/中的adobe-linux-x86_64.repo中的priority=10
现在可以安装adobe的Flashplayer插件了
# yum install flash-plugin
4、atomic软件仓
1、安装atomic源
